Redundancy with boost CB scheme Data sheet Input: AC 230V/115V, DC 210-375V Output: 24V/5A High overload current, no switch-off Quasi-Wide-Range Input N+1 redundancy, RDY relay contact Input Input voltage AC100-120/220-240 V (switchable), 47-63 Hz (85-132 VAC / 176-264 VAC, 210-375 VDC, see also „Output: Continuous Loading“) < 2.6 A (switch in 115V position) < 1.4 A (switch in 230V position) • DCin at open output typ. 5 mA (preserves battery sources) Inrush current Quasi-Wide-Range Input: With the switch in the 230V position the power supply unit operates at low and moderate loads (until 3 A) at any input voltage between 95 and 264 V AC. Note: At DC input, always leave the switch in the 230V position. Input current To be fused with a 10A, B-type 'circuit-breaker' switch based on the usual thermomagn. overload sensing principle (used anyway to fuse the input lines). In addition, the unit contains an internal fuse (not accessible). Rated output voltage For balanced current sharing during parallel operation: Soft characteristic (25.2 V DC ±2% at no-load, 24 V DC ±0.5% at nominal load, almost linear characteristic curve) Output noise suppression Radiated EMI values below EN50081-1, even when using long, unscreened output cables.

Data sheet Start / Overload Behaviour Start-up delay Rise time – no disconnection, no hiccup if overloaded – high overload current (up to 1.9 INom), Vout is gradually reduced with increasing current. – 6A short-term, at 45°C or forced cooling even continuous Advantages: • High short-circuit current, giving large ’start-up window’: unit starts reliably even with awkward loads (DC-DC converters, motors). • No ’sticking’ such as can occur with fold-back characteristics • Secondary fuses operate reliably Output voltage Vout [V] Overload Behaviour • Special PULS Overload Design (see right diagram)...
